Patients who go into cardiac arrest outside of the hospital and are subsequently treated with PCI should not be included in the facilities' reported mortality rates, according to an American Heart Association scientific statement published online in Circulation. The cases should be tracked, however, according to the AHA statement. Hospitals had expressed concerns that the majority of such high-risk patients arrive comatose, receive aggressive care and frequently die from non-cardiac causes, yet are included among STEMI patients under government reporting mandates, said Dr. Mary Ann Peberdy of Virginia Commonwealth University, who led the writing committee.
